Northwest Territories, and the
Nunavut mainland. The
60th parallel north is a
circle of latitude that is 60
degrees north of
Earth's
equator. It crosses
Europe,
Asia, the
Pacific Ocean,
North America, and the
Atlantic Ocean. In
Canada, the 60th parallel forms the southern mainland boundary of the
northern territories of
Yukon,
Northwest Territories, and
Nunavut with the
western provinces of
British Columbia,
Alberta,
Saskatchewan, and
Manitoba. Accordingly, "north of 60" is an expression often used for the territories. The
60th Parallel Territorial Park is on
Mackenzie Highway between
Alberta and
Northwest Territories and it has a visitor centre there in the homeland of the
Yellowknives Dene First Nation and the
North Slave Métis Alliance. Between 1776 and 1950, the 60th parallel formed the southern limit of the
Royal Greenland Trade Department's exclusive monopoly on trade near the
Dano-Norwegian and later
Danish colonies of
Greenland (1776–1782) and
South Greenland (1782–1950). Although it lies approximately twice as far away from the Equator as from the
North Pole, the 60th parallel is half as long as the Equator line, due to the
cosine of 60 degrees being 0.5. This is where the Earth bulges halfway as much as on the Equator. At this latitude, the
Sun is visible for 18 hours, 52 minutes during the
June solstice and 5 hours, 52 minutes during the
December solstice. The maximum
altitude of the Sun is 53.44° on 21 June and 6.56° on 21 December. The maximum
altitude of the Sun is > 15.00º in October and > 8.00º in November. The lowest latitude where
white nights can be observed is approximately on this parallel. During the summer solstice, nighttime does not get beyond
nautical twilight, a condition which lasts throughout the month of June. It is possible to view both astronomical dawn and dusk every day between August 22 and April 21.
Around the world Malachy Tallack wrote a book,
Sixty Degrees North: Around the World in Search of Home, about his travels along the general line of the parallel, starting and finishing at
Shetland. Starting at the
Prime Meridian and heading eastwards, the parallel 60° north passes through: :
